A condition characterised by dilatation of the bronchi (see BRONCHUS). As a rule, this is the result of infection of the bronchial tree leading to obstruction of the bronchi. Due to the obstruction, the aﬀected individual cannot get rid of the secretions in the bronchi beyond the obstruction; these accumulate and become infected. The initial infection may be due to bacterial or viral pneumonia or to the infection of the lungs complicating measles or whooping-cough. Once a common disease, immunisation of infants against infectious diseases and the use of antibiotics have greatly reduced the incidence of bronchiectasis. (See CHRONIC OBSTRUCTIVE PULMONARY DISEASE (COPD).)
Treatment consists of postural drainage of excessive lung secretions, and antibiotics.
